18 With a partner write some statements of your own.Prisms: 8 statements using 4-digit numbers and multiples of 30,40 and 50.Spheres:6 statements using 4-digit numbers and multiples of 20, 40 and / or 50.Tetrahedra: 5 statements using 3 or 4-digit numbers and multiples of 20 or 40

19 Draw the following in your books:I will roll a die 6 times. Each time you should place the number rolled in one of the boxes so that the number statement is true.We will play this several times.

20 Q. Which two 3-digit numbers could you make with these six digits that will have the greatest difference between them?Q. Which two numbers will have the least difference?

21 By the end of the lesson the children should be able to:Compare and order numbers, understand and use the symbols:

27 Order these temperatures:20 degrees 6 degrees14 degrees 40 degrees28 degrees 2 degreesQ. What type of weather would you link with each temperature?

28 Copy these pairs of temperatures into your book and ring the one which is lower :-7 , , -8, , -3, ,-12Make up some pairs of temperatures to test your partner:Prisms do 10 using a range from 25C to -25CSpheres do 7 using a range from 20C to -20CTetrahedra do 5 using a range from 15C to -15C

29 Put these temperatures in order in your book starting with the coolest:Q. What is the highest / lowest temperature?Q. What is 10C cooler than 3C?

31 Q. What is the difference in temperature between Moscow and Buenos Aires?Look at, then complete, Activity Sheet 1.2When you have finished test your partner with some other temperature differences.

32 On another day in June when the temperatures were different two places had a temperature difference of 15 degrees.Which two places might they have been?What might the temperatures have been?EXPLAIN!We are going to record your results.

33 Draw this table in your books:Place 1 and temperaturePlace 2 and temperatureDifference

34 By the end of the lesson children should be able to:Use negative numbers in the context of temperature.

35 To be able to order a given set of positive and negative integers. L.O.1To be able to order a given set of positive and negative integers.To develop calculator skills and to use a calculator effectively

36 Sequence these numbers in your books in ascending order:-13 5Q. Which is the smallest number?Q. Which is the largest number?

38 Q. If I start at 32 and count back in steps of 7 what will the first negative number be?Copy into your books and predict the first negative number for each of these sequences:start step back predicted number24 517 319 8

39 L.O.2To be able to solve a problem by representing and interpreting data in tables, charts and diagrams.

43 Using small crosses plot the temperatures for Brussels on the grid.Do the same for Irkutsk using a different colour.

44 Answer these: Q. When was it coldest in Irkutsk?Q. When was it warmest in Brussels?Q. What is the difference in temperatures in March?Q. Which month has the greatest temperature difference?Q.
